Question

Find the circumference pls help.

Answer 1

Equation for circumference is c = 2(pi)r

r = 1/2(d)

d = 20

So…. r = 1/2(20) = 20/2 = 10

Going back to circumference equation

c = 2(pi)(10) = 2(3.14)(10) = 62.8

Answer 2

Answer:

A - 62.8

Step-by-stexplanation:

The formula for circumference is C=2πr

• C (circumferece) divided by 2 equals your r (radius) wich is 10

• plug in 10 for R use the following formula (c=2πr) to get your answer
• you should get 62.83185 which rounds to 62.8

Your welcome :)
